The title is misleading (a lie to be accurate). The diver is just fine. This happened in Maui. Quote:

"While scuba diving recently off Maui's rugged Nakalele Point, John Hoover discovered what it feels like to be sucked into the abyss, which in reality was merely a torrent of bubbles as part of a powerful surge generated by strong surf. Nobody was injured during this seemingly harrowing diving experience, according to the description posted with the soundless clip."
